A doghouse is to be built in the shape of a right trapezoid, as shown below. What is the area of the doghouse? A right trapezoid with top side 7 feet and height 7 feet. The bottom side is extended to the right with 3 more feet.

24.5 square feet
59.5 square feet
70 square feet
147 square feet

70 square feet

Step-by-step explanation:

This is because the correct formula for this problem is: base x height

Using this formula, you first have to find the base of the trapezoid. Since the square's  base is 7 ft, and the triangle's base is 3 ft, you add these together and get 10 ft as a base. For the height, you need the square's height which is 7 ft. Then you multiply and get 70 ft.
